Rails - Sep 2008 - [Help] How to pass multiple arguments to a method in a worker?

Hi, guys,
I ran into a problem while I tried to pass more than one parameters to a 
method in the worker class, it fails, from the backgroundrb log, I found 
that:

  You have a nil object when you didn''t expect it!
  You might have expected an instance of ActiveRecord::Base.
  The error occurred while evaluating nil.[]

Seems the args is nil, but a hash I passed in my controller. From the 
post: 
http://rubyforge.org/pipermail/backgroundrb-devel/2008-April/001668.html, 
it should be a hash if there are multiple arguments. Here''s what I did:

In my controller:
def blah
  MiddleMan.worker(:hard_worker).send_mail(:args => {:recipient => 
''blahblah-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org'', :subject
=> ''BlahBlah''})
end

In my worker class:
def send_mail(args)
  emailer.send_mail(args[:recipient], args[:subject])
end


Is there anything wrong?

Additional info:
ruby-1.8.6
backgroundrb 1.0.4


All the best,
Hao Liu

Just send the parameters as a single hash:

send_mail(:recipient =>
''blah-C/VviX8sKfI@public.gmane.org'', :subject =>
''BlahBlah'')
